Application filed July 21, 1916. Serial No. 110,597.

' To all whom it may concern:

I works are accessible, gas burners are cur ployed for this purpose withgood results. However, in the operation of linotype machines in thesmaller towns difliculty arises in keeping the metal in the properconsistency where no gas works are provided, and various forms ofdevices for burning gasolene have been utilized with little success forthis purpose. One of the most common constructions heretofore usedconsists of a burner adapted to be fed with gaseous vapors positionedbeneath the melting pot and having.

connected therewith a vapor conducting pipe leading up under the throatof the crucible, and having at its end an auxiliary burner, but it hasbeen impossible to get satisfactory results from this ,structure in viewof the fact that the flame is not spread a sufi'icient distance' overthe throat of the crucible and the burner is not positioned at theproper point with respect to the mouthpiece of the crucible to maintainthemetal passing theresage through the conducting tube and. prevents thesupplying of the proper mixture to the burner underlying the mouthpiece.

It is an object of the present invention to provide a simple gasolenevapor burning attachment for machines of this character consisting of amain fuel burner directly underlying the crucible or melting pot andhaving a vapor conducting tube extending up-- wardly therefrom beneaththe throat of the pot, to a point near the mouthpiece and thence outthrough the side of a jacket surrounding the pot, where a detachableburner is fastened thereto and underlies the mouthpiece of the crucible,this burner together with the main burner keeping the type metal in amolten condition at all times to enable the successful operation of themachine.

A further object of the invention is to provide a heating attachment inwhich the main heating burner underlying the melting pot is separatedfrom the burner disposed beneath the mouthpiece, that is to say, thatthe relatively small burner underlying the mouth piece always produces asmall steady. 'flame and is not subject to the draft created by the mainburner passing beneath the throat of the crucible.

In the drawings, I will illustrate the preferred embodiment .of myinvention in which- Figure 1 is a front View. Fig. 2 is a top plan view.Figs. 3-4 are detail views.

Referring now more particularly to the drawings wherein like referencecharacters indicate corresponding parts, the numeral 1 designates acasing surroundingthe melting pot or crucible 2 havin disposed thereinthe ,usual pump and cylin er .3 communicatingwith the melting pot andprovided with a throat 4 leading upwardly from the pump and terminatingin a spout 5. The spout 5'as well as the pump and throat are of theusual conventional construction and a detailed description thereof isnot necessary. In machines of this character it is necessary that themetal within the melting pot be maintained in a molten condition, andwhere gas works are accessible'this is very easily accomplished.However, when the linotype machines are placed in smaller towns it isnecessary to use gasolene as a fuel for burners disposed beneath themold and much difficulty has been encountered in providing a structurewhich will prevent the metal from cooling prior to its discharge fromthe mouthpiece of the throat. It will, of course be apparent that if themetal should become cooled before its passage from the crucible theoutlet or mouthpiece will be clogged and the operation of the machinestopped. To provide a structure overcoming these difliculties I dis osebeneath the crucible a gasolene vapor urner of any conventional formbeing fed by a generator 7 disposed beneath the casing of'the machineand supported thereby. A needle valve 8 controls I Specification ofI.etters Patent. Patented Ngp, 211, 119116,

the supply from the generator and as the generator is of any approvedtype a description thereof will not be given. It will,'however, be seenthat the gasolene vapors introduced to the burner 8 will be ignited, andthis burner consists of a conical cap 9 pro.-

-vided at its lower end with a series of small fuel openings, and thepurpose ofthis burner is to maintain the metal in the. cruciblein amolten condition.

To prevent the-metal from cooling duringits passage through the throatof the crucible" and prior to its discharge from the mouthpiece, Iprovide an auxiliary. burner 9 p6 sitioned beneath the mouthpiece of thethroat and fed by means of the vapor conductin pipe 10 attached to anopening in theupper end of the conical burner cap 9 and passing upwardlybeneath the throat of the crucible to a point near the outer endthereof.- The feeding pipe 10 then extends at right angles through anopening in the casing D and hasat its-free end a coupling member 11.at:-

tached thereto and provided with a cut off valve 12f To the couplingmember is at-. tached a joint 13'extending forwardlyof the machine to apoint near the outlet, of the mouthpiece, and detachably connected tothis joint is the small auxiliary burner 9 having a plurality ofvaporoutlets 15 therein which directly underlie. the. mouthpiece of "the 5throat and extend entirely across the throat;

The burner is supported at its free end by a plug 17 fitting therein andprovided With an extension 18 engaging a socket within the casingsurrounding the burner. While this is the preferred means for supportingthe burner, it will, of course, be understood that any suitablesupporting device may be used.

From the foregoing, it will be observed that the vapors passing from theburner cap 9 will be conducted to the auxiliary burner by the pipe 10which for ,the major portion of its length extends below the throat ofthe crucible and therefore the vapors passing to the auxiliary burnerwill.

never condensate as they are maintained in the proper condition by theheat passing from the throat of the crucible. The valve 13 of any'desired construction, its purpose ing to control the amount of vaporpermitted to pass to the auxiliary burner to produce a small and steadyflame to prevent the metal from congealing prior to its discharge. Withthis type of burner the overheating of the various parts of the maehineare eliminated as the flame is always small and steady.

The casing 1 surrounding the crucible is secured in place by the setscrews 10', three being shown for the purpose of illustration,

one of the set screws engaging a lug 19 projecting from the cruciblewhile the other fastening screws are secured to the forward 5 endof themelting pot as disclosed in Fig.

momeo 2;. In order to preserve the heat within the crucible a packing ofasbestos or other insulating 'material is disposed around the sides ofthe crucible between the surface thereof'and the casing. 1

In 'a burner attachment of this character it is highly desirable thatthe auxiliary burnerbe in no wayalfected by the draft.

created by the main burner, and to this end the casingl carries nearitsforward end a web 22 closing the-space between the lower portion ofthethroat and the casing and supporting the burner'S and the burner 9, sothat theflame produced by the auxiliary burner-will always besteadyandis not subject to the draft created by the mainburner andpassing throughthe flue between the thev webfs being integral withthe casing,
